When Phelps is tracking Varsi and Andrea in the car, a tracking map shows the car traveling north on Army Street. According to the dialogue, the car turns east on Commonwealth but the map has a different name for the street although it has been partially erased.
After Varsi takes Andrea as a "hostage" they pass a Gulf gas station whose prices are 27 9/10 and 29 9/10. After turning "east on Commonwealth" they pass the same station on the opposite side of the street and the prices are now 28 9/10 and 31 9/10. Later, after Jim and Willy separate from Barney, Phelps is shown across the street from the same gas station whose prices now read 26 9/10 and 28 9/10 (the pedestrian crossing sign and a "Zachary" sign are the same in all three scenes).
Andrea Do you really think I'm planted on you, that I'm KGN?
Varsi: I'd rather apologize for a mistake then die for one. I apologize.
